An update to the Availability Management Pack has been released (05.0.5000.0001).
This corrects several issues, one which could affect new installations of the Availability Management pack where the ReliabilityAnalysisReporting task could return status 0x80040e37 (E_NOTABLE) during execution due to the fact that a required view (SC_Class_Availability_View) does not exist in the Datawarehouse. The Availability Reporting.akm file has been modified and will need to be re-imported. Required computer groups will need to be re-associated with the rule group as discussed in the MP Guide. Once the AKM is imported and associated to computer groups it may take several days before the SystemCenterDTSPackageTask creates the required SC_Class_Availability_View and the ReliabilityAnalysisReporting task executes successfully.
The Availability Reporting database components (MOM_MRAS.MSI) have also been updated to include an improvement in data processing which will allows faster generation of first time reports.
